Tuning an 0411 Swapped 454 Big Block GMT400
ฝัง
- เผยแพร่เมื่อ 24 ก.ค. 2024
- Last time I showed you guys the wiring process of converting this 1999 K2500 Big Block Truck from the black box PCM to the more powerful 0411 LS1 style ECM. This will have many benefits in the long term, from optional 3 bar speed density, a higher RPM limit, and a whole lot more. This process starts with a 2002 Chevy Express operating system and L31 calibration, which has to be tweaked a little to work with the 454 L29. I use HP Tuners software to do this, but the beauty of the 0411 swap is you can also use EFI Live as well.

Thanks for the support guys, y'all are the best! Can't wait to add some horsepower on this big block with a good cam, some headers, and a few other goodies!
I wonder if this will work on a LS with a 8L90 or 10L90.
Gen 6 and Gen 7 BBC were LS like.
Im not sure if yours is a Gen 5 with peanut ports.
You can use the gear wizard to edit the ppm on hp tuners. Just need to know the tire sizes and gear ratio. they also have a tire size calculator in the tools tab. Keep up the great work man!
Hey LT I have a question that maybe you can help me with I have a 98 Chevy Tahoe 5.7 l I have put on a oil catch can from the PVC valve and it's working but am I hurting my motor by doing this?
Does it matter what the 0411 pcm comes out of, or will any one work?
Any chance you would be willing to share a copy of the tune you created for it. I'm fixing to do the same swap on my 97 and just bought hp tuners.
Having owned a 5.7 96 and now a 7.4 97 I gotta say its really cool to see some work like this being put into one step by step..
it seems like nowadays, everyone's first step is to do an LS swap, but I like doing things a little different
So freaking professional you should shoot for a collaboration with someone so ur name will get out there faster
I've been thinking the same thing lately. The content and personality is there, just needs a push. A collaboration with a bigger name would probably help. It boggles my mind how LT doesn't have a few hundred thousand subs.
You are exactly right turbo something for whistling diesel or something like that
Mike Finnegan has a pretty awesome C10 build happening currently.. Truck guys like truck stuff, whether its 2wd or 4wd as LT has shown many times. I bet that'd be a sweet colab.
that would be!
He was on trucks! On power nation for x amount of years. He’s in the know with folks lol
Just think when those people realize he is on TH-cam it will skyrocket
Glad i found you on here lt power block is not the same without you!
Thanks for watching both here and there!
LT you have always been one of my favorites of the power block. I am glad I found your channel , keep up the videos !
thanks a ton!
I'm trying this as well, definitely going to take me longer than it took you.
Love your channel love your content thank you
Wow, these little tips are stuff we would never learn on our own! Nice job!
That big weight of relief when it fires up after doing all that work!
Very cool episode, I hope everyone else is getting as much as I am out of these kind of videos. You’re doing a great job of giving people a real world experience of how to do theses kind on projects or at least what goes into doing it.
Awesome video
Great quality and very detailed
I like how you didn't edit out some of the missteps along the way so we can learn from them
Your the right source for my 96 2500 Silverado 454, thanks for all you do!
Love your work man! Always so informative! Keep up the awesome job!
Keep the tuning content coming ! Thanks also for showing mistakes and remedies. That’s one of the reasons why I enjoy your channel .
Thanks! Will do!
Who needs a valentine when you got LT to watch 🐐
Great video. It was always great watching what you did on television but this showcases your talents alot better and more completely in my opinion. Thanks for all the hard work.
Thanks for watching! It’s appreciated
This was so cool!! Youre kinda like "hacking" these things. I love OEM+ builds like this
LT wish we was neighbours mate. Thanks for the HPtuners walk through.
watched your videos a good 15 times to get ready my upgrade
LT you my friend are a genius. I've always wondered myself if this was possible
Learning something everytime I tune in to the video you post on your the channel.
thanks!
@@LawrenceTolman you are welcome and I enjoy your hands on, hard work, and determined spirit. Enjoy your day tomorrow.
You obviously know your stuff, and you're really good at explaining complex information in an easily understandable way.
thanks! its appreciated
Always a good day when I see your upload. Very interesting as always.
Thank you! Cheers!
Astros and Avalanches had the 0411 as well. I got a couple of mine from both.
Love the videos LT 💯 can’t wait for the next one
Appreciate it
In time you will be able to explain the codes and how you got rid of or got it to learn what it should. Bright young guy with a resume of experience that is growing by leaps and bounds. Great upcoming week to you and enjoy doing what you love to do and consider taking on a older mechanic like me to help. LOL, I had to throw that last couple of wording in for your upcoming business and speed shop. God bless you and your family and enjoy doing what you love to do.
Wow!!!... best explanation of hp tuners I've seen. As a gm tech I've always wanted to get into hp tuners. By using gm diagnostic tools have given me a complete understanding of how gm pids are viewed and how gm systems are used. Thank you now I believe I can get started!
Wow this is great I've got 97 7.4 watched tons of ls stuff. Great info!
thanks!
This is awesome! I just picked up a 96 k1500 with the 5.7 and have been looking around for tuning options for the sbc instead of just ls swapping it. Continue this type of content
If your interested in going in on the deepend you could get an Edelbrock pro Flo system it's vastly superior too the fuel injection system that they came with infinitely more tuneable and a much better intake manifold too
A lot of technical details in the beginning. But LT does it all. The dude is sharper than a laser. Anyway, can’t wait to see the rear top fly off. I think this thing will end up what the avalanche should have been all along.
So awesome man! Thank you for sharing the info!
I know its been a while, but one other option for copying data from one file to another in a compare (besides licensing both and segment swapping) is to go to the red and blue differences view which shows you the value of the difference where identical values are zero. It doesn't work for all tables but for most you can just select all and set the value to zero which only changes the value in the original file to match the compare. Just found the channel and looking at some of the interesting older videos, great job...
Thanks. Missed you on Power Nation, finally found your here. You gained a subscriber today. 👍
glad you found the channel and thanks for subscribing!
Thanks really enjoy your info that you share and even the failures.
just trying to keep it real and show the whole process!
Thank you so much for both of these vids! The Ugly truck and Burb vids will help me decide if I should 8.1 swap my 99 K3500 with the motor I have laying around or if I should just rebuild the 454. Thanks!
great video, i really enjoy this tuning.
Glad you enjoy it!
It’s alive. Nice
can't wait for the tune episode, wondering the difference 😁
No, LT.
You’re the best!
👍🏼
Love the recap and content.
Just an FYI the fail safe for no coolant temp should be -40 degrees F. This failsafe allows the engine to be properly fueled when the air density would be worst case scenario (ie -40) and therefore would never run the engine lean
because it was getting full voltage rather than none, the ECM thought the temp was maxed out, and it will add a little fuel at hot temps to cool things off also...
@@LawrenceTolman
Gotcha.
Crank relearn can be a pain in the ass for sure... had the same issue using a mail-on tune with a programmer in my 9-7x Aero with the LS2. Ended up using a Aeroforce gauge to get it to work myself.
i never got the relearn to work in hp tuners on a 0411
For change the gear and speed on HP tuners just need to go edit and gear/tire wizard and enter the tire size and gear and automatic change the speedo info and the trans shift points for the new gear and tire size
yup, that also works
Ya I'd be lost for sure 😂 this is where I'm stuck paying for a tune 😂
Your channel is doing good. Keep up the great content.
Thanks, will do!
100k subs before 4th of July. Calling it.
I hope you're right!
Man, you are the best!
thanks!
Hey LT, If you ever want to dial in those shift points I highly recommend using the BlueCat Trans Tool. It's a free software you can find on the HPTuners Forums. Easy to use, and works wonders for drivability.
Got a copy of bluecat saved to my computer!
Love the video man!! Hopefully my 98 c3500 cclb dually will get swapped but seems like a lot of work Lolol
its not terrible, a few solid hours but its pretty straightforward
Hey LT, you have to read this. Under the dash beneath the steering wheel, there's a small rectangular box mounted on the firewall. Kind of looks like a big rectangular relay. Unplug it and you won't have to listen to that annoying dinging ever again
Do you have a email ? I just looked under my dash and am trying to figure which one it is
th-cam.com/video/02SWv6QXYH8/w-d-xo.html skip to 1:25
Good idea!
I unplugged mine years ago. I was under the dash trying to figure out some wireing and discovered where the sound was coming from. I pulled it out and laid it on the trans tunnel and it a been there since.
@@skylarreid1284 thanks man ! Gonna check this morning
Great video! I need to do this swap on my 98 3500
You should!
Just bought a 411 pcm from a 2002 express van today. Paid $43.75 for it and the connector plugs. I'm swapping a 2000 ym L29 into my 84 K10 with a SM465/NP205.
Keep it up. I think this one should get a whipple.
That would be cool!
So I have to tell you, leave as a Burb. These are crazy good as overland vehicles.
@LawrenceTolman One thing you missed in this video related to the alternator is to disable the L and F terminals under System/General/System Options. Disabling the codes doesn't disable the idle control routines that rely on alternator control and feedback. Not disabling those options or connecting those wires WILL adversely affect idle stability.
I did this swap on my 98 P30 L31 a few years ago using TunerPro RT and PCM Hammer. I also have HP Tuners. TunerPro is better for setting up an OS to start with, changing VIN, etc to avoid buying extra credits from the greedy bastards at HP Tuners. HPT is better for logging and tuning. If you haven't looked at TunerPro, It's definitely worth checking out.
I had one small issue with my swap. My post-cat O2 sensors were mixed up after the swap. I'm not sure if the spreadsheet was wrong or if the P30 harness was made incorrectly. It didn't cause any noticeable drivability issues or MIL, but I could see the effect when graphing the O2 sensors using Torque. One sensor would stay high most of the time and the other would stay low most of the time. It seems that the PCM tries to command one bank at a time slightly rich to check sensor response and catalyst efficiency. With the sensors swapped, the test would hang until the other bank went a little rich. Unplugging one of the sensors confirmed that they were wired to the wrong bank. I repined the sensors to the correct bank and the problem went away.
Pretty awesome dude and only 2 wires off
yup, got pretty lucky on that one
Since it’s cold in your area you probably didn’t think about this. The auxiliary cooling fan IFO radiator may be controlled by the computer. You don’t want to have any cooling issues this summer especially if you’re keeping the A/C.
My ‘85 K30 has an OEM aux fan and it sure helps when you’re in traffic or other low speed conditions.
I’m so glad I found your channel! I’ve been a big fan of your work for awhile and project red tide was awesome and was one of my favorites! Have you managed to get your hands on one of the old school Whipple Superchargers’s for the 7.4L? Are you planning to do the 24x conversion? I hope so, I’d love to see both!!!! Please keep the content coming!!
I'd love to do the 24x and coil near plug conversion. As far as the whipple, those are super hard to find it seems like
Kevin at KSR down in Florida would be a great guy to talk to about what your doing with these trucks.
I have a ‘97 7.4 that had this 0411 swap a few thousand miles after a professional engine rebuild (it ran ok with the old computer) I had full head work, RV cam, roller lifters, rockers, lightweight coated pistons, bored over 0.030, forged crank, new injectors (ac delco) new distributor, wires plugs, etc, and the only shop in town that can dyno tune, did the ecm swap and dyno tuned it, and it runs like garbage, it won’t even tow a 4,500 lb trailer above 55 mph without screaming at 4K rpm’s.
Sorry to hear that. Sounds like something is way off!
@@LawrenceTolman thanks, there are three tuners in the whole state, one of which did the work I’m not pleased with. Are there any dead giveaway questions I could ask that would rule them out quickly? Thanks for the vids, you’ve done to your old burb pretty much everything I’ve dreamed of doing to mine!
thats a good question I don't have a great answer to. I would just have a conversation with the prospective tuner about your setup, and see how they react. also, reach out on Facebook in your area, and get recommendations for a good GM tuner
Just run the 4 wires to the cluster to set up the PRNDL, it's way easier than it sounds. With your skills probably 30 minutes. As someone else said, use the speedo wizard, way easier. Great job on the pinout, only one pair of switched wires is nice work 👍
yeah, the four wires aren't that big of a deal, I probably should've run em. As far as the speedo wizard goes, I've used with mixed success, it seems to be more accurate (in my experience) to manually calculate the values.
@@LawrenceTolman
That makes sense it would be more accurate. Keep showing the HP Tuners stuff, I sure wish I had that kind of basic info available when I first started! Btw, very happy with Comp 01-412-8 and many other mods.
Lt I watch you and the all the guys and gals from power block I enjoyed and still enjoy watching you and all the car guys on TH-cam you should go vacation in Florida and meet up with cleetus and them guys at fasterproms
that would be a fun trip for sure
Tunercat was the software that tuned the black ecm back in the day.
Loved the video. My only problem is finding the right information for the wiring vs the connection vs the computer. Any thoughts you can throw my way?
good job - getting shit done!
thanks!
Awesome 😎👍
All three codes is for the cluster can system the warning system in your cluster in the newer models talk about this play on the left side of the cluster of a 2002
Very excited for this build! Love ugly truck but I cant wait for more of this build!!! With the time going into the 0411 swap I'm sure you are staying efi. Long term are you keeping the stock intake or swapping for something else to make more power?
I'd possibly swap to another style of multi port efi intake like an Edelbrock Pro Flow XT, but we'll see
Thanks for the videos on this 0411 swap. Guess I'll be looking for one and some connectors. I have a 502ci I want to swap in as the L29 I think spun a bearing 🤔 . I'm aiming to keep the stock EFI setup, changing fuel pump, regulator, and injectors.
Would a L29 fuel map be the best starting point and do a complete fuel table +11% (7.4 to 8.2) to get me going with the stock L29 injectors as a starting point to get it running?
Super informative, thank you!
I've got a 2000 7.4 L21 in an 8500 bucket truck. Can I swap a 0411 ECU into it?
Great work. Really liked the explanation on all of the HP Tuners tweaks. There is so much in there. I’ve only ventured in to the trans portion on mine. Tweaking shift points, tcc setting etc... As far as the PNRDL setting, I had a hell of a time when it was set to none. I wired the stock sensor up for PN only to give the PCM a ground signal in park and neutral and it seems to be a lot happier. Low speed part throttle was really wonky until I made the change. If the shift shaft on your trans long enough to put a PN switch from a 60e or 80e?
yeah, the trans already has a range switch on it actually, I just wanted to avoid running four more wires if I could avoid it simply by changing one parameter in the tune. once I Did the re-learn, it seemed to run just like it did before
@@LawrenceTolman Perfect! Glad it worked out!
Nice
I'm do the same swap on a 96 chevy and 98 gmc I got the pinout sheet for both trucks and the 0411 pcm. My question is do I have to do a segment swap on the 0411 because they came out of a 02 chevy blazer with a 6v to put the 02 chevy express van files on?
Nice!! Very interesting.. :-)
Thank you! Cheers!
Nice job, LT. All those wires and only 2 reversed.
lots of opportunity for things getting mixed up, but yeah, not bad having only two be off
Just in case, never hurt to be prepared.
So with this small step done, is there an 8.1 swap or even an LSX 454 swap ? In the future, it’s going to be a GMT avalanche after all
Great vid! Did you have any issues with the new ECU not talking to the Transfer Case Control Module? I did a similar swap and my 4x4 is all jacked up, that's the only thing I can pinpoint.
no I didn't, but because I switched to a NP241 the transfer case control module is disabled. However, from when I did the conversion on the transfer case, I was pretty sure the TCCM is a standalone system and only sends a signal to the ECM to let it know its in 4wd or in low range. The one thing I havent tried yet is driving in low range, and because the express van tune is from a 2wd vehicle, not sure it will be paying attention to the low range input.
I have a 98 gmc sierra push button 4x4, and a 411 psm I bought from a salvage yard and I haven't had the chance to mess them yet. but I was wondering will the 4x4 still work after the swap is completed?
You need to get Stacey David to do a cameo.
Oh man.. this is great! Cant wait to see how you tune for the modifications you make. I'm looking to 0411 swap an L31 engine to be able to handle increased compression, better heads, cam & intake. Looking forward to your next video, as always!
Edit: To tune w/HP Tuners, assuming a compatible laptop/computer, what do you need to be able to pull tunes, view & edit, and load new tunes to the PCM? Do you need to pay per vehicle or per tune? Aka: once the PCM is 'yours' are you free to modify it unlimitedly or? Thank you!
thanks! you'll need a windows based laptop to run HP Tuners on, and you are free to "read" as many vehicles as you like, so you can save the tune files to reference later on. For modifying the file and flashing the ECM, you need to license both the file, and the computer. If you read a tune from your truck, modify it, and flash it back in, one license covers both the ECM and the file. If you do like I did and find a new file to flash on your computer, you need to license the tune file and the ECM separately (two licenses, total of four credits for my project)
@@LawrenceTolman Thanks for the reply!
You can take the 2 tunes in HP Tuner and use it's tine comparator and it will show the differences between the tunes. Or are they not comparable?
You can (sort of) but many of the tables have different axis labels and different scaling, so it won’t be a direct copy and paste. But some of the data is close enough to to get a good comparison from
Just finished my 0411 swap on my 97 1500. The truck is running great but will not read on HP Tuners or OBD2 reader. I double-checked and the class 2 serial data is in the correct spot. I also checked the fuze for it and it checked out. Any help would be appreciated!
Question. My 99 Yukon has the L31 5.7 Vortec motor. Will the Express van tune work from the start without any mods?
How you doing you're doing a great job I wish you could do my truck
Nice work LT! Two wires had to be flipped around not bad, if I did it wouldn't be pretty! What do you think that would cost if you had to have some one do it$$$$$. Again good job!!!
You may find some dealerships will cost you almost $1200 that's including the labor fees. IDK where my bosses son found the ECM for the dump truck at work but it cost him a little more than $600 pre programmed and all he had to do was give the VIN number
So its best to find a 0411 in an express van (L31) for a direct swap for a Tahoe/Yukon with the L31?
Would you be willing to share the "base" file needed to be flashed onto the 0411 to get me going on a stock 97 454 L29? How can I get a hold of you for some questions if you don't mind? Thanks in advance and awesome work!!
Any chance you’d be willing to share that tune file? Trying to help a buddy with this exact swap. He’s driving on the 5.7 van tune and it is not ideal, but got his truck running in an emergency when his black box pcm failed. It’s a 98 vortec 7400 as well but a crew cab dual. Appreciate the video!
Can you add a link to the wiring info you purchased?
yea the credits are a bit high ..i herd it takes say 4to 6 credits if you want to tune engine and transmission on certain stuff any thoughts .i got swap mom 1997 4x4 truck asap 383 going in soon
Do you have contact info for the guy that got you the pin out spreadsheet? Doing a stock L29 out of a 2000 k3500 4wd into a 1997 c1500, would love to just get the 0411 ecu from him with tune loaded with the mods I need to make it plug and play with the truck.
LT, how is the 0411 with the L31. I'm wanting to keep the L31 and swap out the spider for different EFI.
its pretty much the same exact swap, and the tune will be spot on if you find a stock express L31 tune file as well.
LT, please do yourself a favor and ALWAYS have your laptop plugged into power when flashing a PCM! Don't ask me how I know!!
yeah, that could be bad if it looses power midway through a flash
Do you have the tune file or atleast remember where you got the 7.4 file?
Currently have my 97 swapped and running, would like a better ve table to start with
Did you post your custom tune on the repository?
Great video! Would you be willing to email me the tune you ended up using for this pcm swap? I am wanting to swap an 0411 into my 96 k3500.
Did you upload your motor file on HP tuners?
Looking to do the 0411 swap also.
So ive been wanting to up my OBS knowledge and workaround, the ECM stuff and the HP tuners info is GOLD to me, since youre planning on building the suburvalanche out ( which im ectited for) i wanted to ask about the ABS/ Braking system, what you will do/ plans and if you happen to make videos about it, money, so at the end of the day if you respond cool, if you end up making videos on this, even better, but at this point, if anybody has 2 cents to add, that would be great
my thought was to do the 2500HD brake upgrade for the 2001 trucks and discs on the back
@@LawrenceTolman Alright! , Im looking forward to the video(s) im especially looking forward to keeping the parking brake, do you think you'll end up swapping out the brake master cylinder or do the big block OBS all use hydoboost? I guess we'll cross that bridge when we get there.
When are you actually charged for those credits, when you burn it into your ECM? Also do you get charged when you have to go back in for changes?
buy them before you start the project, and they are stored in the interface. you only get charged once, and once you license the file you can make as many changes as you want.
👍👌 I have one ecu 0411 camaro 2001 its work for swap to lt1 97 camaro
